WALTER W. STOPPLE, OF ALMA, MICHIGAN, ASSIGNOR T0 LITTLE GIANTHAY PRESS COMPANY, OF ALMA, MICHIGAN, A. CORPORATION.

'BALING-Pnnss. f Y

To all whom it may concern:

Be it known that I, WALTER iV. SToPrLE, a citizen of the United States of America, residing at Alma, in the count-y of Gratiot and State of Michigan, having invented certain new and useful Improvements in BalingFresses, of which the following is a spec ification, reference being had therein to the accompanying drawing.

This invention relates to baling presses especially adapted for use within buildings for pressing material, such as paper, into bales to facilitate shipping of the same.

The principal object is to produce a baling press that will occupy the minimum of floor space and which is so constructed that a fire within the press cannot get beyond the press, and a fire within the room in which the press is stationed, cannot gain access to the contents.

Tn carrying out the objects of the invention generally stated above, it is contemplated providing a strong and serviceable structure which includes a supporting frame which has a charging hopper at the upper portion, and a body formed of front and rear doors and end panels, the doors and panels being so connected to the frame that when closed provide a tight and rigid body which will withstand the maximum of pressure from the inside, such as is incidental to the forming of a bale, and which, when opened, expand so that a bale can be readily removed.

In addition to the foregoing prominent features of the invention, the improved press includes a novel bottom for the press in which means are provided which permit the bale ties to be readily passed under the bottom of a bale, a plunger which is also provided with means which permit the bale ties to be passed over the bale, and novel means for operating the plunger which can be readily operated to set the plunger upon the top of the material to be baled, and then operated to place the material under compression to form a tight and compact bale.

Tn carrying out the invent-ion as generally stated above, it will be understood, of course, that the elements thereof are necessarily susceptible of a wide latitude as to struetural arrangements and details of parts, but one simple and practical embodiment is Set Specification of Letters Patent.

forth in the accompanying drawings which illustrate a practical press embodying the principles of this invention.

In said drawings :-Figure l is a perspective View of the improved baling press. Fig. 2 is a front view thereof. Fig. 3 is a view in elevation of one end of the press. Fig. 4 is a similar view of the opposite end of the press. Fig. 5 is a transverse vertical sectional view. Fig. G is a horizontal sectional view, the body being shown closed. Fig. 7 is a similar view, the body being shown opened. Fig. 8 is a longitudinal vertical sectional view. Fig. 9 is a det-ail perspective View of the supporting frame of the press. Fig. 10 is a detail view partly in elevation and partly in section of a foot lever for operating a controlling pawl. Fig. 11 is a detail fragmentary sectional view of part of the machanism for initially operating the plunger. Fig. l2 is a perspective view of the plunger. Fig. 13 is a fragmentary sectional view, taken on line A-A, Fig. l2.

Referring to the accompanying drawings by numerals, it will be seen that the improved baling press comprises a skeleton supporting frame that is formed of the corner standards l which are connected at their bases by the horizontal front and rear and end bars 2 and 3 and at their upper ends by the similar bars 4 and 5. The base bars 2 and 3 are preferably heavier than the upper bars 4 and 5, and said base bars have the feet 6 rigidly fastened thereto which rest on the loor or other supporting surface.

The standards l and the bars 2, 3, 4, and 5 in the present example are formed of angle metal which provides the anges to which the body and the hopper are bolted, as will be presently explained, but it is to be understood, of course, that other types of bars may be employed when necessary or desirable.

The standards l at each end of the supporting frame are connected by the upper and lower horizontally arranged supporting bars 7 which are provided with the inwardly projecting sockets 8 in which the vertically arranged trough-shaped housings 9 are rigidly fastened. Said housings 9 ex tend from the base of the supporting frame to a point well above the top of said frame. The upper bars 4 of the supporting frame have the lower edge of the hopper 10 bolted or otherwise rigidly fastened thereto, the ends of said hopper being provided with vertical slots 11 into which the open sides of the housings 9 project. Said housings are bolted or otherwise rigidly fastened. The' projected upper portions 12 of the ends of the hopper 10 have vertical slots 13 formed therein over which the blocks 14 are fastenedv and which carry the lugs 15 which are provided with threaded -openings for the adjusting bolts 1 6. Said bolts engage thel bearings 17 which are slidable in the slots 11. A shaft 18 is journaled in the-bearings 17 and has its projecting ends equippedy with the sprockets 19.. The rear of the hopper is closed and the front open. A pair of wings or flanges 20 project laterally from the open front of the hopper, one wing being at each side thereof, and said wings projectwell beyond and overhangI the front of the press. A vertically swinging. door 21 is hinged to the base of the front of the hopper, said door filling the spaces between the wings 20 and is held in a closed position by means of a gravity latch 22 that is carried by a bar 23 that extends across the top o-f the hopper. The wings 20 are provided on their inner surfaces adjacent their lower outer ends with rests 24 which support the door 21 a horizontal position when open. Obviously, when open, the door 21 forms a shelf which facilitates the placing of material in the f' press. The side wings 20 form the ends of the hopper, as will be clear, and are bolted or otherwise rigidly fastened to the upper portions of the housings 12.

The corner standards 1 carry upper and lower hinge ears 25, in which the angular ends 26 of the elongated bracket hinges 27 are pivot-ally mounted. Said bracket hinges overlapA and are rigidly fastenedA tothe outer surfaces 'of the front and rear doors 28. Said doors swing horizontally and are arranged in` pairs, onev pair at the front and the other pair at the rear; The free vertical edges of said doors are provided with angle strips 29 which abut .when the doors are closed so that no crack or' opening is left through which lire could pass. 'The opposite edges of said doors are bent at right angles to provide the vertical flanges 30, which are overlapped by the angular por'- tions 26 o-f the bracket hinges 27,. and said flanges overlap portions of the end corners of the skeleton: supporting frame. The free vertical edges of said flange are equipped with angley bars 32 which abut similar bars 33 carried by the outer vertical edges of lthe movable end panels 34.

'lhe end panels 34 are carried by the hinge brackets 35, the' angular freeends of which are pivotally connected tothe door bracket hinges 27 at points adjacent the' connection of said door brackets with the standards 1.

This manner of hinging the end panels 34 to the doors 28, causes the panels to swing away from the skeleton supporting frame when the doors are opening, and to swing 3 close to the frame when said doors are being l"closed, so that when open, the pressure on the bale is released, and when closed, the 'bale is tightly embraced. The inner vertical edges of the panels 34 are equipped with the angle bars 36 which abut the outer side lsurfaee of the housings 9 so that the press is sealed at those points when the said panels are closed. The sockets 8A of the supporting bars 7 .have the outer surfacel of their inner ends provided with cana: surfaces 37 which are engaged by the lugs 38 at the inner ends ofy the bracketsy 35 and which act ais guides for the panels when swinging to open or closed positions, andl also serve as braces so that the panels willv withstand the pressure of the material being baled. The upper end bars- 5 of the support-ing frame carry inwardly projecting sockets 39 on which the housings 9 are fastened, the ends of said sockets being secured to the hopper 10. The under' surface of said sockets 39 are equipped with cam surfaces 40 which engage the upper end 0f the angle bars 36 carried by the panels 34 to assist the cams 37 in holding'. and guiding, the said end panels.

The end bars 3 of the base' of the supporting frame are provided with bearings 41 in which the power shaft 42 is mounted. The projected outer ends of said shaft 42 have the ratchet wheels 43 fast thereon. Pivot lugs 44 project laterally from the front portion of the bars 3 and have the cranks 45 mounted thereon. Said cranks are provided with sockets 46 for the elongated hand levers 47, and are also provided with pawls 47a for engaging the ratchets 43, so that when the hand levers 47 are rocked, the pawlswill, rotate the ratchets and similarly actuate the power shaft 42. Said pawlsare preferably formed of a pair of parallel straps which are pivotally connect` ed to opposite sides of the cranks 45 and have theirl outer ends connected by a pivot bar; This arrangement provides loops which straddle the ratchets 43 so that the pawls are always in position to be operated by the levers 47 to actuate the said ratchets. Shaft 42 is also equipped with sprocket wheels 48 which are located beneathI the housings 9 and in alinement with the sprockets 19 of upper shaft 18. The sprockets 19 and 48 are connected by chains, said chains being in two sections 51 and 52. Chain sections 51 are heavy ones and extend through the housings 9 and have one of their ends shackled to the pendent lugs 53 car ried by the ends of a plunger beam 54 which extend into said housing. Said sections 51 pass around the sprockets 48 and are connected to the sections 52. The sections 52 are light ones and pass over the sprockets 19 and are connected to the upper ends of said lugs 53.

At one end, shaft 18 carries a sprocket 55 which has a chain connection 56 with a sprocket 57 mounted on a shaft 58 journaled in a bearing 59 carried by one of the end bars 5. Shaft 58 hasa collar 60 fast thereon which is provided with a notch 61. A second collar 62 is loose on shaft 58 and is provided with spaced parallel hinge ears 63 in which a hand lever 64 is pivotally mounted. Said lever has an angular extension 65 at one end for engaging the notch 61 of collar 60 so that by rotating the lever, sprockets 55, 57 and chain 56 will rotate shaft 18 to raise the plunger. A hand grip 66 is carried by the free end of lever 64. A gravity pawl 67 is provided for normally locking sprocket 57 against a movement that raises the plunger.

Two of the hand levers 47 have been shown, one at each end of the press, and said levers are employed for rotating the chains 50 to cause the plunger to compress the material in the press. Said levers operate upon the heavy chain sect-ions 51. A pawl 68 is pivotally mounted on a pin 69 projecting from the base of one end of the supporting frame and normally engages the adjacent ratchet wheel 43 to prevent reverse movement thereof. Said pawl is equipped with an arm 70 provided with a laterally projecting end lug 71 that is slidable in a longitudinal slot 72 formed in a foot lever 73. Said lever is pivotally connected to one of the feet of the press and equipped with a treadle 74 which facilitates the lever being rocked by the foot of an operator to release pawl 68 from the ratchet 43.

The plunger beam 54 may be of wood or other suitable material, but the plunger 75 carried thereby is preferably formed of sheets or plates of metal having upturned flanges 76 at their ends and intermediate grooves 77 which are parallel with said flanges 76. The flanges 76 of the plates abut when the plates are assembled and are suitably fastened together and reinforced by the angle strips 78. The outer ends of said plates are braced by the connecting bars 79, and said plates are further reinforced by the straps 8O that extend over and are fastened to the beam 54 and have their ends fastened to the bars 79. The grooves 77 are formed in the face of the plates of the plunger and facilitate the passing of the bale tying means over a bale.

rllhe bottom 81 of the press is formed of sheets or plates of metal having end flanges 82 that are held in abutting relation by suitable fasteners. Each plate is provided with a groove 83 through which bale tying means are passed beneath a bale.

The body of the press is composed of the bottom 81, the front and rear sets of doors, and the end panels, and said doors are retained in locked positions by means of the vertically arranged upper and lower latching bolts 84 which are slidable in the lugs 85 and engage the openings 86 of the lugs 87 carried by the bars 2 and 4 of the supporting frame.

One door of each set of doors is equipped with the bolts 84, and said bolts are operated by the hand levers 88 that are pivoted to said doors and have their angular heads 89 provided with links 90 which are pivotally connected to said bolts. The lugs 87 are provided with lips 91 which overlap the edge {iange of the adjacent door so that said door cannot be opened until the bolts 84 are released. The levers 88 are guided by and have a limited pivotal movement between the guide straps 92.

It will be seen that this press provides a body that expands when the doors are opened so that a bale can be readily re moved. It will also be seen that simple means as provided for initially operating the plunger to set the same on the material to be pressed, after which simple compressing means are operated to cause the plunger to eXert a great pressure on the material to form the same into a tight and compact bale.

rI he end lugs 53 of the plunger beam 54 depend in the form of rigid arms which form efficient means for attaching the chains 51 to said beam. Said arms snugly, but slidably lit within the housings 9, so that in the event the material fed into the press is not evenly placed, the plunger will not be tilted thereby. This arrangement provides simple guiding means for the plunger so that a bale of uniform density will be made.
